Semantics WG report Measurement Semantics MEASEM D 1

Semantics WG report Measurement Semantics: “MEASEM” D 1 AHM, Park City, UTMay 15, 2014 Presenters: Mark Schildhauer & Xixi Luo

Participants ● ● ● Mark Schildhauer Xixi Luo Line Pouchard Deborah L. Mc. Guinness (remote) Margaret O’Brien (remote)

Ontology Design Patterns (ODPs) for Observations and Measurements All W 3 C OWL: OBOÉ (ecology), EQ/PATO (genomics), O&M (OGC, ISO 19156)

Focus of D 1 Semantics in Phase II Semantics of Measurements: . . . binding raw data values to concepts drawn from ontologies. . . often through metadata. . . using W 3 C standards for annotation-PROV, OA. . . to facilitate resource discovery and interpretation through enhanced precision and recall of searches

Tools for Semantic Annotation of Measurements ● Semanteco ● annotation of CSV’s ● OBOÉ design pattern ● D 1 Phase I product, and other ongoing work at RPI. . . ● GITHUB, Web interface available

Tools for Semantic Annotation of Measurements ● Semantic ● annotating EML-described data objects ● OBOÉ design pattern D 1 Phase I product, and ongoing work of NCEAS, LTER, others

PHASE II: MEASEM, PROV, and Ms. TMIP* ● Focus on semantic clarification of Ms. TMIP data: ○ Measurements as expressed in Model Outputs and Observational Data ○ Clarify definitions and inter-relationships among Measurements ● Develop Ontologies with relevant Concepts ● Annotate Ms. TMIP data products to Ontologies (tools needed!) ● Develop UI’s enabling enhanced Precision and Recall in searches ○ Expect enhanced interpretation of variables by Broader Community ● PROV and MEASEM WG both using W 3 C Semantic approaches ○ Shared technology infrastructure, tools, and syntaxes (onts, annotations) * Ms. TMIP== Multi-scale Synthesis and Terrestrial Model Intercomparison Project http: //nacp. ornl. gov/Ms. TMIP. shtml

MEASEM, PROV, and Ms. TMIP * focus on measurement semantics

MEASEM and Ms. TMIP Possibly also develop semantic “Taxonomy of Models”?
